' This code has been directly CONVERTED from C# into CV
'
'* This tutorial covers creating a mesh viewer.
'*
'* It is similar to the native tutorial, but different.
'* Since much of the gui and xml stuff is not in the
'* .NET wrapper yet, I decided to use winforms and
'* the .NET xml mush for those portions of the tutorial.
'*
'* Some of this tutorial is based on the work Braneloc did
'* on Tutorial 14.
'*
'* The tutorial also includes some other interesting stuff
'* that I decided to play with.
'*
'* For instance, you can change the driver in the middle of
'* looking at a mesh.
'* Since I used .net 2.0 & VS2005, you can also move the
'* toolbar around the form.  (A new freebe in .net 2.0)
'*
'* DISCLAIMERS:  This will not work with .net 1.1.
'* The reason is that some of the controls I used in this
'* tutorial are not available in .net 1.1.
'* Most of the controls that I know have changed are the
'* menu and toolbar stuff.
'* The new stuff now has names like "MenuStrip",
'* "ToolStrip", and "ToolStripMenuItem", etc.
'* Seems kinda silly, I know, but I'm sure someone over
'* in Redmond really thought they had a great idea.
'*
'* Also, MS changed their xml api in .net 2.0.
'* The xml part of the tutorial might port to .net 1.1
'* just fine, but I'm not sure and not ambitious enough
'* to check it out myself.
'*
'* BUGS:  Yeah, I'm sure there's a few in there.
'* I notice when switching drivers, the app will
'* sometimes lock.  I haven't quite figured out why yet,
'* but it seems to have something to do with Irrlicht
'* having a null device.EventReceiver.  Also, the
'* debugger will sometimes point to a problem with fonts
'* in this case.
'*
'* The winforms event responses are very doggy.
'* I tried a couple of Application.DoEvents() in the render loop,
'* but they didn't seem to help much.  I may
'* look at this in the future.
'*
'* FINAL NOTE:  If you happen to find any fixes for any of the
'* bugs listed above or any new ones you find, share them with
'* the community.  Post about them on the forum, and update
'* the Wiki.
'*
'* Getting it working: 
'* Create project as windows form, and add the 2 Irrlicht DLL's to it.
'* (This file is the only one needed in the project)
'* Add open.bmp and help.bmp from the Irrlicht media directory to the
'* resources.
'* You'll probably need to rebind the images to the toolstrip, hint,
'* open is the one on the left..
